Total! whom t may concern.

Be it known that I, JOSEPH ANToNUccro, States, residing at Oakland, inthe county of Alameda and State of California, haveinvente'd a` new anduseful Gas-Burner. of' which the following is a specification in suchfull and clear termsas willenabl'e those skilled in the art to constructand use the same.

This invention relates to a combina-tion gas cock and gas burner usedfor heating purposes and an object ofthe invention i's Y to produce anefficient mixingdevice whereby the air and gas will be properly mixed atall times, even though the supply of gas .may be very much reduced.

It will be uuderstood'by those skilled in .the art that where a needlelvalve is used to reduce the quantity of gas passing to the mixingchamber that the veloc1ty of flow -v `of the gas is so greatly retardedand interfered with that the mixingv is very ineffectually done.Therefore, with this invention means are provided whereby the nozzlewhich delivers the gas to the mixing chamber has a chamber ofconsiderable size im mediately adjacent it, the regulation beingaccomplished by the valve vwhich does not interfere wit-h the openingfrom the nozzle into the mixing chamber.

Another object of the invention is to providemeans whereby the pilotlight will have gas supplied to it prior to the supply of gas to theburner proper. 1

In the drawings in which the same numeral of. reference is applied tothe same portion throughout the several views, Fig ure-1 is a verticalsectional view through the burner, mixing chamber and pilot light, Fig.2 is a'plan view of the burner, mixing chamber and pilot light, Fig. 3is a view in end elevation of the pilot light, gas valveV and burner,Fig. 4 is al vertical sectional View of a modilied form of the gassupply valve, the plane of section being chosen to illustrate the,lrelative position of the two ports in said valve, Fig. 5 is a verticalsec' tional view of the gas valve transverse to the valve plug, one of:the ports therein being shown in full lines and the other in dottedlines, and Fig. 6 is a front view of said valve.l

The numeral 1 represents'the gas supply pipe to which the gas regulatingvalve 2 is secured in the usual manner. The gas regulating' valve has asmall nozzle 3 and has external and internal threads at 4.Revolublewithin the valve is a frustoconical plug 5 having the handle 6to rotate the same. A screw 7 holds this plug in its proper place in theValve and the plug 5 is provided with a stop 8 to prevent it frombeing.turned more than a given amount, the fixed part of the valve having astop 9 which thestop 8 strikes. This plug supplies the pilot light withgas and its handle is so placed as to. be

operated with the left hand. Between the plug 5 and the screw the .valvethere is a than the plug 5 nozzle 16. This threaded portion of plug 11slightly larger which supplies gas to the ther-ight.

The object of placing the valve plug handles in the mannerI shownl is totake advantage of an almost' universal habit of people. All right handedpersons when undertaking to light a burner of this character will strikethe match in the right hand and will reach out with the left hand toturn the gasonin the burner. This naturally brings `the left hand to thepilot light handle. The

next operation of the person is to throw the ma'tch away whereupon theright hand will be used, and in this instance the burner valve will bewithin convenient reach at once. It thus becomes almost a certainty thatthe proper valve will be opened rst.

Supported-by the valve casing is a mixing chamber 12, said mixingchamber having a conical portion 13 and having arms 13, which have anopening therein to receive the end of the valve casing. The mixingchamber is curved upwardly as shown at 14 and has a pan like top 18. u

Resting upon the top 18 is a shallower pan shaped member 19 having aflange extending over the edge of the member 18, lugs 2 0 spacing saidmember a short distance away from the member 18 and a short distanceabove the same.

The pilot light is supported on the nozzle 3 as indicated at 21 and ithas a long nozzle 22, extending into proximity to the edge of the burnertop 18. 'Screwed within. the valve is a gas nozzle 16, said gas nozzlehavingan opening 17, which is of sufficient size to supply the givenburner with the necessaryamount of gas.

It will be observed that between the valve supplying the burner with gasand the end of the nozzle where the opening 17 is placed,

tov

n plug has a screw 11 toho-ld f v1t 1n place and lts handle 11 is placedat there is a considerable chamber which is for the purpose of alwaysretaining a supply of gas so that the gas flowingfro'm the nozzle. tipwill always move therefrom at a. good velocity to be adequately mixedwith the air in the mixing chamber whether at a high or low pressure; aneifect that is dificult to accomplish when the needle valve at theopening 17 is used.

In Figs. 4, 5 and 6 a valve is shown which accomplishes the objects ofthe two valves vshown in the preceding gures. In these figures the valvecasing is indicated at 25, a threaded portion ofthe valve at 26 and thenozzle leading to the pilot light at 27. This valve is also threaded at28 to receive a pipe 29.

The valve proper comprises a frustoconi- 'cal plug 30 held in place bymeans of a screw 31 and operated by means of a handle 32 at the left ofthe valve, the same as is used for the pilot light in the precedingfigures. This valve plug has two ports therein, one

-25 at 33 and one at 34, said ports being so spaced apart and shaped asto supply the pilot light with gas prior to the time the burner issupplied withgas, note Fig. 5, in which gas is flowing fully to thepilot light.

`within the mixing chamber,

` my hand this 3 Further movement of thev valve'supplies the burner withgas, and when the burner is receiving a further 'supply of gas afurtherm'ovement of the valve will cut 0E the pilot light from thesupply 'of gas altogether.

Having thus describedmy invention what I claim as new and desire tosecure by Letters Patent of the United States is as follows.:

In-a gas burner, 'the combination of a shallow pan, a 'mixing chamberleading from the lower side of said pan, a smaller flanged pan looselylit-ting into the rst pan to cause the mixed gasto be dischargedtherefrom in an annulus, a 'gas supply pipe, a cut off valve connectedwith the pipe and niixing chamber, and-a removable gas tip substantiallyas described. A

In testimony whereof I have hereunto s et .the presence of the twosubscribed'witnesses.
